SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 405,153, dated June 11,1889.

v Application filed September 20, 1888. Serial No. 285,878. (No model.)

To aZZ w/wm it may concern.-

Be it known that I, GEORGE P. FENNER, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented new and useful Improvements in Sheet-DeliveryApparatus for Printing-Machines, of which the following is aspecification.

This invention relates to an improvement in sheet-delivery apparatusserviceable in printing-presses, as set forth in the followingspecification and claims, and illustrated in the accompanying drawings,in which Figure 1 shows a side elevation of a sheetdelivery apparatus.Fig. 2 is an end elevation of what is shown in Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates a type-bed or type-cylinder, andB an impression-cylinder. A sheet being fed from the feed-board C istaken by the gripper D and carried between the cylinders A B. Afterbeing thus printed the sheet is taken by the gripper E on the deliverytraveler or tapes F, which move in the direction of arrow 1, Fig. 1.Rollers G H carry the traveler or tapes F, and the cam I trips thegripper E, so as to cause said gripper to take a printed sheet from thecylinder B. The cam K trips the gripper E, so as to cause said gripperto drop the printed sheet. In Fig. 1 the gripper E is shown as beingabout to be tripped to drop a printed sheet L.

M is a carriage having rollers N 0 supporting a traveler or tapes P. Onthe shaft of the roller 0 is loosely mounted a gear-wheel Q. A toothedwheel R is firmly secured to the shaft of the roller 0, and a pawl S issecured to the gear-wheel Q, so that a clutchconnection is formedbetween the gear-wheel Q and roller 0. When the gear-wheel rotates inone direction, the pawl S glides over the teeth of the wheel R Withoutturning said wheel R or the roller 0; but when the gearwheel rotates inthe opposite direction the pawl S engages the teeth of the wheel R androtates said wheel and the roller 0 and imparts motion to the traveleror tapes P.

A rackT is applied or fixed to the apparatus so as to engage thegear-wheel Q. The carriage M has a rack U engaging the'gear-wheel V. Twogear-wheels V, Fig. 2, are shown adapted to engage two racks U, one ateach side of the carriage M; but one gear-wheel V and one rack U mightbe made to answer. The gear-wheels V are oscillated by a gear- Wheel IVand rack-bar X. A roller-stud'Z and cam Y impart an oscillating orreciproeating motion to the rack-bar, and a pin or arm a, fixed to thepress or machine,holds the rack-bar in gear with the wheel W.

The operation of the device is as follows: YVhile the sheet L is beingdropped by the gripper E onto the carriage M the carriage is at rest,the cam Y being so formed as to allow the carriage to remain at rest atsuch moment. When the sheet L has been droppedonto the traveler or tapesP of the carriage, the rack-bar X rotates the gear-wheels V so as tomove the carriage toward the receivingtable 1). During this motion ofthe carriage, the rack T rotates the gear-wheel Q in such direction thatthe roller 0, and the tapes P, with the sheet L thereon, remain at rest.WVhen the rack-bar X makes its return-stroke, the carriage M is movedfrom the receivingtable I) toward the impression -cylinder B. Duringthis return motion of the carriage M the rack T rotates the gear-wheel Qin such direction that the roller 0 is rotated to im part a progressivemovement to the traveler or tapes P, that are to move that portion ofthe carriage-tapes which carries the sheet L toward the receiving-tableb. The sheet L, restin g on the tapes P, is by this progressive mo tionof the tapes caused to move off the carriage M onto the receiving-table1).

Suitable gears 0 cl, Fig. 2, convey motion between the cylinders AB, andthe gears d e convey motion between the cylinder B and the roller G,about which pass the tapes or traveler F. The carriage M is supported byways f and rollers g, Fig. 2, so that said carriage can be readilyreciprocated by the rackbar X.

As the cam Y oscillates the carriage M positively in both directions,the use of a spring or weight to restore the carriage to its originalposition can be dispensed with. The traveler or tapes F, with theirgripper E, constitute a simple and effective delivery apparatus fordeliverin g the printed sheet from the impression-cylinder 13 to thecarriage M.

hat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with an impressioncylinder, a delivery apparatus,and a receiving-table, of a reciprocating carriage located under andmoving independent of the delivery apparatus, and on which the printedsheet is deposited by the delivery apparatus, and mechanism,substantially as described, for positively moving said carriage in bothdirections, substantially as described.

2. The combination, with an impressioncylinder, a delivery apparatus,and a receiving-table, of a reciprocating carriage located under andmoving independent of the delivery apparatus, and on which the printedsheet is deposited by the delivery apparatus, and a cam or itsequivalent for actuating said carriage, said cam being arranged to allowthe carriage to be at rest while a sheet is being deposited on saidcarriage, substantially as described.

The combination, with an impressioneylinder, a delivery apparatus, and areceivi11g-table,of a reciprocating carriage provided with a traveler ortapes on which the printed sheet is deposited by the delivery apparatus,said tapes having a progressive movement during the return movement ofthe carriage, and rack, gear, and cam mechanism, substantially asdescribed, for positively moving the carriage in both directions,substantially as descrilmd.

4. The combination, with an impressioncylinder, a delivery apparatus,and a receiving-table, of a reciprocating carriage provided with atraveler or tapes on which the printed sheet is deposited by thedelivery apparatus, a rack and clutch-connection for imparting to thetapes a progressive movementduring the return movement of the carriage,and a rack, gear, and cam mechanism, substantially as described, forpositively moving the carriage in both directions, substantially asdescribed.

5. The combination, with an impressioncylinder, a delivery apparatus,and a receiving-table, of a reciprocating carriage provided with atraveler or tapes on which the printed sheet is deposited by thedelivery apparatus, said tapes having a progressive movement during thereturn movement of the carriage, but being motionless during the forwardmovement of the carriage, a rack on the carriage, a gear engaging therack, a cam, and a conneetin g rack-bar between the cam and gear,substantially as described, [for positively moving the carriage in bothdirections, substantially as described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
